A

24 is the upper mandrel-shaft, and 25 is the mandrel carried thereby. 26is a central bearing for shaft 24, and 27 1S a reduced end. of shaft 24,which passes through the journal-head 16 of bracket 16.

28 1s a leaf-spring secured to bracket 15 and bearing on the reduced end27 to give the shaft 24 a tendency to move longitudinally. Thecentering-pin 21 engages a journal-recess in the opposite end of shaf t24.

29 is a pulley keyed to shaft 24, and 3U is. a band assing around saidpulley and around a simi4 `r pulle 31, carried by the shalt 2, by meansof whic 1 the shaft 24 will be driven in the same direction and at thesame speed as the shaft 2.

32 and 33 are respectively the record and blank mounted, respectively,on the mandrels 25 and 4. By adjusting the position ol' the pin 21 itwill be observed that the shaft 24, carrying with it the. mandrel 25 andrecord 32, can be adjusted longitudinally to insure the properengagement of the reproducing-stylus therewith.

35 1s a carriage of any suitable construetion clamped at 36 to aguide-tube 37, which operates on the customary guide-rod 38.

39 is the customary spring-ar1n secured to the guidetube 37 and carryingat its forward end the driving-nuts 4U, which are adapted to erwage withthe rotary driving-screw ll), and t iereby push the carriage along.

41 is a suitable guide on the front portion of the carriage whichengages the front bar 42 of the ordinary phonographmachine. The carriagewill therefore slide upon the rod 38 and front bar 42.

45 is a supporting-bar formed with a longitudinal slot 46 and secured tothe lug 47 of the carriage 35 by means of' the clampingscrew 48, whichpasses through the slot 46. The forward end of the bar 45 is formed witha yoke 5U, in which is pivoted a weight 51 on the pins 52.

53 is the reproducing-lever carrying the reproducing sapphire stylus 54and pivotally connected at its end 55 with the forward end of thepivotally-supported weight 51. The lever 53 has a right-angled extension53", to which is pivotally connected the recording lever or arm 56,which carries in a suitable socket formed in one end the sap hire refcording-stylus 57. The forward en of lever 56 rests on a rounded orsharp edge 58 of the supporting-arm 59, which is pivoted in the slidmgblock or bracket 60 and is provided with a V or other suitable spring 61and an adjusting-screw 62 for regulatin its position and adjustin theposition ci the styli. The recording-styus 57 is preferably formed of acylindrical link 57 and an enlarged frusto-conical cutting-head 57h,which may be hollowed out, asl shown in Fig. 5.

The sliding block or bracket 60 is mounted in a suitable slot formed inthe bracket 65 and adjusted forward and back in said bracket by thescrew 66, which engages a lug on the bracket 60. The bracket 65 isvertically ad'usted on the supporting-arm 67 by means ci the screw 68and slot 69.

7() is a telltale-reproduer having a diaphragm of any suitableconstruction from the center of which projects an e re 71.

72 is a thread attached to tie ivot-pin connecting levers 53 and 56 andppassing through the eye 71 and provided at its free end with a smallweight 73.

7 4 is a hearing-tube suitably connected to the reprodueer 7U andadapted to have suitable earpieces attached, by means of which thevibrations of the reproducing-arm can be heard and the proper operationof the device detected.

75 is a short rock-shaft suitably journaled in bearings 76 in the carriae and carrying the rock-arms 77 and 78. he rock-arm 77 carries a rod 79,which passes under the spring-arm 39 and is adapted to lift thedriving-nuts 40` out of en agement with the screw 1() when therock-sliiaft 75 is moved.

The rock-arm 78 extends forward and engages under the extension of thepivot-pin 55, which connects the weight 51 and lever 53 and b v reasonof such engagement disengages the styli from the record and blank. Keyedto the right-hand end of the rockshaft 75 is an operating-lever 80,pivoted at its lower end 81 to a link 82, which latter has a crookedforward end 83, adapted to extend around a pivot-pin 84.

85 is an operatinginger pivotally mounted upon the pin 84 and connectedat 86 with the end of link 82.

87 is a spiral spring attached to lever 8() and link 82 for holding themin the position indicated in full lines in Fig. 2 when all parts are ininoperative icsition or in the position indicated in dotted lines insaid figure when the parts are in o eration.

1n Figs. 6 an 7 I have shown a slight modification of the device foroperatively supporting the styli. In this form of the device the ivotedsupporting-arm 59 has a bifurcatedJ forward end 90, to which theweighted lever 91 is pivoted by means of the pin 92. Thereproducing-lever 53 is pivoted to the outer end of the lever 90 and isalso pivotally connected to the recording-lever 56, as in the preferredform. The forward end of the record-lever 56 rests on the pin 92.

In Fig. 8 I have shown a further modification, in which thereproducing-stylus 54 and recording-stylus 57 are carried 1n oppositeends of a sin le lever 95, which is ivotally mounted in t e forward endof a balanced wei ht 96, pivoted upon the pin 97. 98 is a hee projectingfrom the lever 95, and 160 is a thread extending from said heel over apulai mi and pfovideo with a weight ma', w ich holds the Styli to theirwork ina inanncr somewhat similar to preferred form.

.In Figs, and 10 I have shown the preferred form of reproducing-stylus,in which a forward end of thevlever 105, carrying the stylus 54, ispivoted to the rear portion 06 by means of a pin 107, which engages in aSuitable socket in the lover portion 106 anda lo `small plate 08. Thepivot-pin 107 extends a )proximately at right angles to the tanffcnt oithe cylindrical record at the point which the stylus 54 comes in contactand enables the stylus to readily lind its way into the x 5 groove ofthe record.

It will be observed that the stylus-supporting lovers 53 and 56 areconnected to or Supported from suitable stationary points, which preventmovement in the direction of zo the tangent to the record-blank at thepointl ol contact therewith of the recording-swine. It will also beobserved that the two levers are pivoted together in the lineapproximately perpendicular to the tangent. In recording or duplicating`with my improved machine the tendency of the rotating blank is to movethe recording-stylus out of the wax upon an arc drawn from the point ofpivot connecting the two levers. Movement in this are is prevented breason of the weight and the en ragement o the reproducing-st los 'witht e record which is being copie/i The only movement therefore that thestylus can have is in a line perpendicular 3- 5 to the tan ont at theoint of contact of the stylus wit i the recon this being the frcest andbest motion for producing a perfect record, because it is least affectedby the movement of the record, and the stylus being con- 4o structed andsupported to make a clear shearing cutit wi be obvious that a perfectreproduction of the original record will be obtained.

It is to be understood that I do not limit myself to the specific formsol mechanisms hereinbefore described, but that various inechanical chanes may be made within the scope of the c aims without departing from thespirit of the invention. 5o Having thusfully described my invention, thefollowing is what I claim as new therein and desire to secure by LettersPatent:
